MARTIN L. KISSELL, or SPRINGFIELD, OHIO, ASSIGNOR TO THE P. P. MAsT &ooMPANY, OF sAME PLACE.

HOE FORIGRAIN-DRILLS.

V. 4 To all whom at may concern:

Be it known that I, MARTIN L. KISSELL, a citizen of the United States,residing at Springfield, the county, of Clark and State of Ohio,have'invented certain new and useful Improvements in Hoes forGrain-Drills, of which the following is a specification, referencebeing'hd therein to the accompanying drawings. 1"

This invention relates to improvements in hoes for grain-drills, and hasspecial reference to thefarrangement and construction of those featureswhich enter into the'organization of a spring or yielding connectionbetween the hoe arid its beams or draft-bars. I am aware that, broadlyconsidered, a spring or yielding connection between such hoes and theirdraftbarspby means of which the hoes are allowed to give or deflect whenobstructed by objects which afford greater resistance thanthe normals'trains brought upon th'ehoes as incident to the ordinary operation ofdrilling grain, is old; and therefore wish to'be understood as layingclaim to my improvements in the light of the state of the art as atpresent developed.

In the accompanying drawings, forming a part of this specification, andon which like reference-letters indicate correspondin g parts, Figure 1represents a sectional View of a graindrill and a hoe and its draft-barwith my improvements applied thereto; Fig. 2, an enlarged plan View ofmy improvements in connection with a hoe and its draft-bars; Fig. 3, alongitudinal sectional View on the line w w of Fig. 2, and Fig. 4 adetail perspective view.

of a stop-lever.

' The letterA designates the essential portion of a grain-drill frame'ofany approved construction, but preferably of the type manufactured andsold by my assignees of this invention, P. P. Mast & Company, ofSpringfield, Ohio, and in which are embodied two adj ustable transversebeams B and O, to which the forward ends of the hoe draft-bars arepivotally connected, the draft-bars alternating from first one and thenthe other of the beams B and C. By preference these draft-bars arecomposed of separate pieces D D, and at their rear ends they areconnected by a pivot-pin E to a suitable part of the wing F, extendingfrom the hoe G, which is of the usual or any SPECIFICATION forming partof Letters Patent No. 404,845, dated June 11, 1889. Application filedFehruary 16, 1889. Serial ITO-300,136. (No model.)

approved type. This wing has a series of holes H for the reception ofthe usual fragile or wooden brake-pin I, the function of which is Wellknown. To the lower forward portion of the Wing F is pivoted two linksJone at either side of the bolt K. These links extend upwardly andforwardly from this pivot-bolt a suitable length, and are pivotallyconnected to the upper forward side pieces of the stoplever L, assuggested at M. This stop-lever is composed of two side pieces L ,a bodyportion M, curved upward at its rear end, as seen at O, and of a shortstout arm P. These several parts are by preference integral, and may becast-iron, malleable iron, or may be forged of iron, or they may beconstructed of steel.

I term the device a stop-lever, because it acts in the capacity of alever and in the capacity of a stop to preserve the normal and properrelations of the several parts by engaging with the under edge of thedraft-bar, as seen at Q in Fig. 3, in which the parts are in normalposition. f' It will-be seen from Figs. 2 and 4 that the arm P islocated nearer one of the pieces L than the other, so as to accommodatethe rear end of the spring-rod R, which is pivotally connected with thearm P by a pin S. The stop-lever is itself pivoted to the draft-bar by apin or bolt T,which passes through the portion 0 and through the piecesL. A clear idea of the arrangement of the parts may be gotten from aview of Fig. 2. The relative position of the pivots K, T, and M willalso be clearly seen from Fig. 3, from which it will be observedthat-the pivot T. is slightly above a line drawn through the centers ofthe pivots K and M. This relation of the 0 pivots, it will beunderstood, is necessary in order to bring the strains sufficiently toone side'of the pivot T to turn the lever on that pivot when the hoe isunduly obstructed, as suggested in Fig. 1, in which a stump is illus- 5trated as located in the path of the hoe. The brake-pin gives away, andthe strains are then thrown upon the spring-rod, the connection of whichthrough the spring U, about to be described, brings the hoe back to nor-10o inal position, as suggested in dotted lines in Fig. 1. The spring Uis of spiral type, and

is placed around the rod Rbetween a washer V, held by a nut NV, and aplate X, secured to and between the draft-pieces D of the draftbar. Ahook Y may be formed on the upper end of the plate X, for engagementwith the device for lifting and sustaining the hoes when not inoperation.

It will be observed that my improved arrangement and construction avoidsthe proj ection of parts to any considerable distance above thedraft-bar, and that when the parts are swung to the position shown inFig. 1 they are all below the draft-bar save the hoe, which is at therear of the axle Z. This arrangement is important and of value inpractice, because it admits of the draft-bars being raised up to theaxle without obstruction from the parts of the spi'ingconneetion,whereby higher stumps and otherobjects can be passed over by the hoewithout breaking one or more parts of the machine, as is the case when ahoe lodges on a high stump, or other high obstruction, and raises thedraft-bar high enough to cause the parts which project above to catch onthe axle before the hoe is over the stump or other object. hen thislatter occurs, some vital part of the machine is almost invariablybroken, and delay and expense of repairs incurred, and this probably ata time when most inconvenient to the farmer. By my improvements,however, this trouble is entirely avoided by the absence of the partsprojecting above the draft-bar when thelatter is thrown up. I

It will also be observed that-the stop-lever L is a cheap and strongdevice, admirably adaptedto its functions, and doing the double oificeof a lever and a stop.

The brake-pin may or may not be used. The holes in the wing are simplyprovided so as to temporarily use the pin in case of breakage in thespring-conn ection until such breakage is repaired.

Having thus fully described my invention,

what I claim as new, .and desireto secure by Letters Patent, is

1. The combination, with a hoe and its draftbar pivotally connected toit, of a spring-rod carried by the draft-bar, a lever pivoted to thedraft-bar at one end, links pivoted to the hoe and to the other end ofsaid lever, a stop constituted by said lever between said last pivots,and a pivotal connection between the lever and the spring-rod.

2. The combination, with a hoe and its draftbar pivotally connectedthereto, of a springrod carried by the draft-bar, a lever composed of anupwardly-turned rear portion pivoted to the draft-bar, abody lookedunder and across the said bar and side pieces at the sides of said bar,and an arm within the draftbar, a pivotal connection between the saidarm and the spring-rod, and links pivotally connected with the hoc andwith the said side pieces of the lever.

3. The combination, with a hoe, its draft-bar composed of two piecespivoted to the hoe, a plate and rod between said pieces, a springbetween the plate and an enlargement on the forward end of the rod, astop-lever composed of a rear upwardly-extending portion pivoted to saiddraft-pieces, an arm extending from said portion andpivoted to said rod,a body beneath and across said draft-pieces and side pieces, and linkspivoted to the upper forward ends of the side pieces and to the hoebelow its pivotal connection with the draft-pieces.

4. A stop-lever composed of a horizontal body portion, side piecesextending above said portion, a rear upwardly-extended part,

and a short arm projecting forward from said part, all of said partsbeing integral.

In testimony whereof I afiix my signature in presence of two witnesses.
